ADOLPH F. W. LORIE, OF DUNEDIN, NEW ZEALAND.

SASH-FASTENER.

SPECIFICATION forming part of Letters Patent N 0. 747,617, dated December 22', 1903.

Original application filed July 2, 1902, $eria1 No. 114,130.

To all whom it may corwermy Be it known that I, ADOLPH F. W. LORIE, asubject of the King ofGreat Britain,residingatDunedin, New Zealand, have invented certain new and useful Improvements in Sash- Fasteners, of which the following is a specification.

My invention relates to an improvement in sash-fasteners, and my present application is a division of that filed by me in the United States Patent Office on July 2, 1902, Serial No. 114,130.

My present invention consists in the features and combination and arrangement of parts hereinafter described, and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a side view of the invention, partly in section. Fig. 2 is a front view, and Fig. 3 is a detail cross-sectional view. Fig. 4 is a detail view of the gravity-hook.

As shown in the said application, the invention comprises a holding device in the form of a screw-bolt 1, passing through a nut 2 and engaging with its end a corrugated strip, which is secured to the upper sash, while the nut and screw are secured to the lower sash, the said screw being set against or withdrawn from contact with the said strip to lock or unlock the fastening. The spindle or shank of the screw has a bent part or crank 9 at its -end through which said screw isoperated.

The bent part of the screw has attached to it a semicircular lever 5, provided with a groove 6. This aifords a curved bearing over which a chain 7 or other flexible operating means passes, which is suitably attached to said curved bearing at the point 8. The chain hangs down at the side of the window and terminates in a ring 9 When the chain is pulled, it moves the semicircular lever in the direction indicated by the arrow, thus turning the screw and withdrawing the same from the strip 1 to thereby release the fastening. This turning action of the screw to release the fastening winds up a coil-spring 10 within the nut, one end of which spring is secured to the screw at 11 and the other end being sesecured to the spring casing or out at 12. On the chain being released the spring automatically thrusts the screw against the strip Divided and this application filed July 29, 1903. Serial No. (No model.)

a bracket 14,fixed to the window-casing. This hook has a Weighted end 15 and an inclined upper edge 16, and when the lower sash is closed the spindle or shank of the screw engaging the inclined edge will tilt the gravityhook aside, and immediately the said screwspindle gets below the point of the hook said hook will swing back into normal position with its hook end over the spindle of the screw, thus holding the same, together with the lower sash, down in closed position. Of course the upper sash may be in a partly open or closed position at this time,and if locked by the screw to the lower sash it will be held firmly in the position to which it'has been adjusted.

I claim--- 7 1. In combination in a sash-fastener, a nut, a screw working through the same to engage a part of the upper sash, a flexible hand operating connection for the said screw and a curved bearing connected with the screw about which the hand operating connection extends and to which it is attached, substantially as described. a

2. In combination in asash-fastener, a nut, a screw working through the same to engage a part of the upper sash, a flexible hand op- 4. In combination in a sash-fastener, a nut,

. crating connection for the said screw and a ascrew working through the same to engage means consisting of a gravity-hook, substana part of the upper sash, and locking means on tially as described. 10 the frame engaging the screw, substantially In testimony whereof I afiix my signature as described. in presence of two witnesses.

5. In combination in a sash-fastener, a nut, ADOLPH F. W. LORIE. a screw working through the same to engage Witnesses: apart of the upper sash, andlocking means on WALTER DONALDSON, the frame engaging the screw, said locking 0. S. MIDDLETON.
